Iron block. I am using 95 M3 LCAs with centered solid bushings. I like it very much but then again I went from torn bushings to solid. The front wheels felt like they where from a grocery cart and the steering wheel shook at moderate braking.

So am I correct in understanding your wheels are actually further rearward than normal? Do you have the M3 caster tops installed?

I am thrilled that you got a nice weight distribution. I guess that's why my car handles so beautifuly, when I was expecting a bit of a monster from the increased nose weight... (I suspect we have very similar handling cars)

Actually, while on the subject, is it true the E30 aluminum lower control arms can be used on the E36? and, if so, how do they compare (geometrically) with the '95 and '96+ E36 M3 LCA's?

I am quite pleased with my 'bastard' front suspension, but I'm always keen to wring that little extra out of it...

The wheels are a little further back now that you mention it.

I haven't changed the strut hats. Not yet anyway.

The aluminum E30 LCAs will fit. Not sure which bushing they use. As you know, 95M3 are centered bushings, +96 are offset. Are they really worth the money for some weight loss?

The car is very well balanced. It does exactly what I tell it to do on the track. Unfortunately I don't always tell it the right things.

I'll be at Mid-Ohio memorial Day weekend. The car absolutely loves that track more than any other.

I tink you are a bit mixed up with the bushings. The 95 is offset, and 96+ are centered. This is why your wheels (with 95 arms and 96+ bushings) are set back a bit.

Mine, on the other hand are 96+ arms with 95 bushings, so they are set forward a bit.
I'm also fairly certain the E30 used offset bushings for the M3 only, as the LCA's are the same for M and non-M cars (as far as I know). Only difference being aluminum for less UNSPRUNG weight. This is a nice place to loose weight, so the suspension can react faster...

For the E36, BMW realized they could just make the arm a bit different, and use the same bushing across the board. I'm not sure if this was the smartest thing, but it allows us to move our front wheels around nicely!
